Bonus Army: Around a thousand World War I veterans amass at the United States Capitol as the U.S. Senate considers a bill that would give them certain benefits.

The Bonus Army was a group of 43,000 demonstrators—17,000 veterans of U.S. involvement in World War I, their families, and affiliated groups—who gathered in Washington, D.C., in mid-1932 to demand early cash redemption of their service bonus certificates. Organizers called the demonstrators the Bonus Expeditionary Force (B.E.F.), to echo the name of World War I's American Expeditionary Forces, while the media referred to them as the "Bonus Army" or "Bonus Marchers". The demonstrators were led by Walter W. Waters, a former sergeant.

The United States Capitol, often called the Capitol or the Capitol Building, is the seat of the United States Congress, the legislative branch of the federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. Although no longer at the geographic center of the national capital, the U.S. Capitol forms the origin point for the street-numbering system of the district as well as its four quadrants. Like the principal buildings of the executive and judicial branches, the Capitol is built in a neoclassical style and has a white exterior.

The United States Senate is a chamber of the bicameral United States Congress; it is the upper house, with the U.S. House of Representatives being the lower house. Together, the Senate and House have the authority under Article One of the U.S. Constitution to pass or defeat federal legislation.
